To all whom it may concern.-

Be it known that I, JOHN B. Knmson, of

Lynn, county of Essex, State-of Massachuf setts, have invented an Improvement in Sole- Edge-Blacking Machines, of which the following description, in connection with the ac companying drawings, is a specification, like letters and numerals on the drawings repre-v senting like parts.

This invention relates to apparatus for applying blacking or other coloring-matter to the edges of boot and shoe soles, whereby the coloring-matter is absolutely prevented from touching the upper or the projecting top of the sole when desired the coloring-matter be- 1 ing applied rapidly and evenly without spatterin My present invention has for one of its objects the improvement of this class of apparatus in general, and more particularly it is an improvement on the apparatus forming the subject-matter of an application, Serialf No. 635,010, filed May 4:, 1597, by myself and others as a joint invention.

I make use herein of a rotatable color-applyin g device having a continuous slightly-yieldiug periphery, as in said application referred supporting standard or column for the appa ratus. Fig. at is a top or plan view of the base the column being shown in section. Fig. 5 is an enlarged vertical section of one of the color-reservoirs-viz., the lower inner reservoir, Fig. 1. Fig. 6. is a transverse section thereof, on the line 00 m, Fig. 5. Fig. 7 is a like view on the line so as, Fig. 5, looking down. Fig. 8 is asection on the line so 00" looking up. Fig. 9 is a sectional detail to be described, taken on the line m 50 Fig. 7. Fig. 10 is a side elevation of the guard or shield shown in section Fig. 5. Fig. 10 is a vertical section on the line a m Fig. 10. Fig. 11 shows in perspective details of the means for controlling the passage of coloring-matter from the reservoir. Fig. 12 is a transverse sectional detail on the line y L Fig. 5,

through the chambered boss in the reservoir;

and Fig. 13 is a vertical sectional view on the line 02 0 2 Fig. 1, looking to the right. I

Referring to Figs. 1 and 2, the head of the apparatus comprises a frame A of suitable shape to support the various working parts and preferablymounted on a standard or column A, having a base A Figs. 3 and 4,

adapted to be secured to the floor or other support. The frame is provided with bearings a for the main driving-shaft B,having fast thereon a gear 0 in meshwith an intermediate pinion B mounted on the frame, said pinion in tnrn'meshing with a gear B fast on a second shaft 13, rotatable in bearings a on the frame. 1 (See 2.) A suitable clutch is mounted on the shaft B, the member B being fast thereon, while the. loose member B is shown as a cone-pulley, retained on the shaft by a collar b the clutch members being thrown out of engagement by means of a tripping device, comprising a trigger b on the member 13, a cooperating spring-controlled studlfl, mounted on an arm 5 fasten arockshaft'b having bearings in the frame A, and provided with an actuating-handle b moved by the operator. This clutch mechanism forms no part ofmy present invention and need'not be further described herein, as any other suitable clutch device may be used.

The color-transferrer is herein shown as a truncated cone T, preferably made of rubber, having a continuous slightly-yielding periphcry. to apply the color to the work smoothly and evenly without streaking or spatter-ing. The edge of the sole is held by the operator against the-rotating transferrer, which, as

shown in Fig. 5, is applied to the reduced held in place on the shaft by a washer 3, se-

cured by a screw 4 tot-he reduced portion of the shaft. The shaft B also has a like transferrer'T secured thereto,eacl1 transferrerhavthey will be described separately, the reservoir D cooperating with the transferrer T and being shown in section, Fig. 0, with detailsin Figs. 6 to 11. Yokes a a, mounted on the frame A, engage the upper ends of the resor voirs D and E, respectively, to steady them,

, on or forms part of the bottom plate D, divided by a vertical partition d5, Figs. and 6, into two cylindrical open-endedchambers, ithe frontwall of the bosshaving a transverse inlet-opening'd, Fig. 6, through which the the reservoir in each case consisting of a cylinder open at its ends, with apertured tops D. EX, respectively.

The reservoir D is shown as threaded, at its lower end to screw tightlyv onto an upturned annular flange d on the bottom plate D, which latter has an extension D provided with a boss d", a screw-bolt d extending through the .boss entering a horizontal notchd in the frame, (see Fig. 2,)a thumb-nut d at'the other end of the bolt. serving to clamp the bottom plate securely in place.v Within the flan ge d an elongated hub or boss 61* is erected coloring-matter passes from the reservoir to i Y the interior of the boss.

A tubularplng (1 (see Fig. 11,) closed at its upper end and having an inlet-port d adapted to register with the opening d of the boss, is inserted in the right chamber of the latter, Fig. 5, and is rotatably held therein by a stop 5, (see Fig. 12,) the edge of which partially enters an annular groove (1" in the plug, the stop being inserted in a recess made in the partitionwall (1 and held securely in place by a setscrew 6. In order to conveniently rotate the plug d, I provide the lower end thereof with a suit-able handle al by which the operator be obvious that by movement of the handle (Z in the direction of the arrow the size of the inlet to the interior of the valve d may be reduced to the desired extent or altogether closed. The valve proper is shown as an open-ended tube (Z inserted to oscillate in the plug d and having attached to its lower end a segment-gear d, which meshes with a circular rack R, as herein shown, said tube (Z having a port (1, (see Fig. 11,) which is at the height of the inlet-port (Z of the plug, the oscillation of the tube causing the port (1 to move back and forth from the inlet-port,

so that the passage of the coloring-matter to the interior of the tube is intermittent. A guard 8, shown as a fiat metal arm, Fig. 8, is pivotally mounted at 9 on a lug 10 of the bottom plate D and is adapted to be swung in under the rear end'of the segment-gear d to hold the tube (1 in place, the guard being retained in position byspringing it between two opposed pins 12 and 13.

The 'transferrer T is located below the reservoir D and the coloring-matter is conducted to the transferrer by a distributer f, shown as a. block having a longitudinal chamber f open along its under side at f immediately gitudinally movable in the chamber to vary the length of the opening f andv thereby control the width of the bandof color onthe transferrer. 'The distributer has a groove f in its top to be enteredby the end of a scr ew stud 1t, threaded into the bottom plate D, a catchf on the distributerbeing movableinto a'groove 15in the studtoretainth'edistributer thereon. A hollow stem f secured to the K above the transferrer. A slide-rod f islon-. 1 1 I latter, enters snugly the valve c1 the lower I end of the stem opening into the chamberf,

while ahole f in the stem is at a level with the port-r to the side of the distributer b'y a screw 16 to smooth the film of color on the transferrer and preventan undue thickness of thefilm as it is applied to the work, adjustment being effected by meansof the attaching-screw. 1

The coloring-matter passes from the reser hole into the hollow stem f and thence down the latter into the chamberf and onto 1 the transferrer through the delivery-opening f of the chamber.

with an inlet-slot c, has but one chamber and,

is made substantiallycylindrical in shape to receive a plug e in every respect similar to the plug (1 and provided with a regulating handle or arm a, while a tubular valve similar to the valve (1 is inserted within the An evener-blade f is attached voir through the slot ct, ports d and d, and

plug, said tubular valve having a segment 6 7 (see Fig. 2) in mesh with a rack Q. The distribute-r g is in its general construction like the distributerfthat is to say, it is chambered, with a longitudinal slot in the bottom of the chamber to deliver the coloring-matter to the transferrer T, said coloring-matter passing from the interior of the valve mech anism to the distributor by means of a hollow stem 9; but I have herein shown the distributer g as provided with two slide-rods and 9 located in the opposite ends of the distributerand cooperating with two scraping or evening blades g and g respectively, which cooperate with the transferrer, as before described, as by such construction I am enabled to control the How of the coloring-1natterindependently at the outer end of and for the main body portion of the transferrer. The bottom plate E, havinga boss 6, held in place on the frame by a bolt e having a thumbframe, and held in adjusted position by a check-nut 37.

When the machine is stopped, it will be obvious that all communication between the reservoir and the distributer may be shut oif by swinging the arms d or e to close the inletp'orts in the plugs 01 ore respectively.

In operation more of the coloring-matter must be delivered to the t-ransferrer when it is thick than when it is thin, so that in'the former case the valve mechanism is adjusted to permit a greater inlet-pass'agef-rom the reservoir to the hollow stem leading to the bearings, and outside of the bearings spiral springs 43 s surround said rods between the inner bearings (see Fig. 1) and collars (1 r adj ustably secured to the slide-rods, so that the tension of the springs may be regulated, the latter normally acting to hold the racks in the position shown in Figs. land 2, with the openings in the ports in the tubes attached to the segmental gears in such position as to close communication between the interior of said tubes and the reservoirs, thus automatically efiecting a stoppage of the flow of the coloring-matter when the machine is not in operation.

. In order to reciprocate the slide-rods q 0" when the'machine is in operation, I have mounted an inclined rock-shaft h in bearin gs on brackets 40 and 41 on the main frame, the

shaft being provided at its upper end with an adjustably attached arm 1L opposite'the inner end of the rack-carrier q, while collars 42 and 43, fast on the rock-shaftbetween its bearings, limit itsllongitudinal movement'in' the latter. A sleeve h is loosely mounted on ihe rock-shaft above the collar 42 and has a rearwardlyextended arm 71?, (see Fig. 2,) which is pivotally connected to a link on, the latter at its lower end (see Figs. 3 and 4) being pivoted to a lever'm fulcru med at'm on a plate M, adaptedto be secured to the floor alongside of the base A of the standard, said plate having upturned ears m m on which are fulcrumed at m and m respectively,

treadlesM M respectively, the forward ends of the boss 61* is provided with'a plug 0 having an inlet-port c and said plug at its upof the treadles extending beneath the lever m at opposite sides of its fulcrum. By depressing the tread end of the treadle M'the link m will .becdrawn down, and by a similar movement of the treadle M the said link will be raised, and thereby the sleeve it will be lowered or raised, respectively. As shown in Fig. 2,"thelink is provided with collars and 51, and between the collars and a fork 52 on the standard A are mounted spiral springs, 3 5 the said springs tending to maintain the treadles in normal position and the rock-shaft in substantially the position shown in Figs. 1 and 2. Hubs n ando are mounted on the rock-shaft h adjacent each other and preferably with spiral springs s ands between said hubs and the collar 43 and arm h, the hub 47. being fast on the rockshaft and having a forwardly-extended arm 01. provided with preferably a roll a and the hub c has also aforwardly-extended arm with an attached roller 0 said rolls being adapted to be moved (one or the other of them) into the path of a cam'H, fast on the shaftB. If the operator places his'foot-on the treadle M the rock-shaft h andthe parts mounted thereon will be lifted to bring the roll 0 into the path of said cam, whereas operation of the treadle M depresses the rock-shaft and its parts to bring the roll 01. into the path of the cam, the

. normal,position of said rolls n 0? being out of the path of movement of the cam. Now when the roll 77. is in the path of the cam each rotation of the main shaft will operate through said roll and the arm n to rock the shaft 71, and'thereby the arm 72/, to the left, viewing Fig. 1, so that the rackscarrier q will be moved to the left against the action of its spring 3, the latter effecting the return movement of the rock-shaft as the cam passes beyond the roll 11?. Similarlyif the roll of is in operative position the rack-carrier 1r will be moved against the action of its spring 8, the-latter returning the arm 0 to normal position or act-' ing to maintain its roll 0 in the path of the cam, the hub 0 being loosely mounted on the rock-shaft, and it will be noticed in Fig. 1 thatthe arm 0 is provided with a flattened face 0 opposite the rack-carrier r. If the transferrer T is in use, the valve'mechanism' thereof will be operated through the arm h and rack-carrier q, whereasif the transferrer T is in use the valve mechanism for the reservoir D will be operated by. or through the arm 0', and it will be noticed that the mechanism is so arranged that the valve mechanism o'f only one reservoir can be automatically operated at a time;

As the coloring-matter will not be thrown or spattered from the transferrer, it is unnecessary to use a shield, but a guard is requi site to protect the shoe-upper, and I have herein provided a guard which at the same timecau effect the application of the coloring-matter to the top portion of the sole extended beyond the'upper, if desired.

Referring to'Fig. 5, the left-hand chamber per end is threaded to receive an adjustable in the plug is arranged a hollow tube 0 hav- B, said gear and tube being held in place by the plate 8,hereinbefore described. The guard is shown as a flat plate having a convexed lower end 70 and at its outer side a chamber 70 with a vertical outlet near its lower end, as at 70 Figs. 10 and 10, the said outlet opening on the flat face of the guard-plate 70, which latter is depressed at 70 to permit the coloring-matter to flow thereover. The chamber W has attached to its upper end a long hollow stem 70*, which is extended up into the tube 61 said stem having, as shown in Fig. 10, an elongated opening 70 therein to register with the openings 0 and c. I have herein shown the upper end of the stem (see Fig. 5) as provided with a screw-cap 70 the head of which projects over the upper end of the tube c and thereby prevents withdrawal of the guardstem, and between the screw-cap and the top of the adjustable cap 0 of the plug is interposed a suitable spring S, which normally presses the guard downward, the tension of the spring being adjusted by means of-the' cap a. The stem 70" has secured thereto a col lar k which is adapted to rest against the head of a stop-screw 7c, threaded into the bottom plate D and held in adjusted position by a set-screw 70 By varying the position of the head of the stop-screw the downward movement of the guard under the influence of the spring S is regulated, and it will be seen from the drawings that the guard itself is located immediately adjacent but not in contact with the outer end of the transferrer T. The opening 70 in the hollow stem is elongated in order to provide for the longitudinal movement of the stem in the tube a. The coloring-matter flows onto the inner face of the guard-plate at 70, which when in use enters between the upper and the sole, coloringmatter flowing from the guard onto the top of the sole, while the edge of the latterhas color applied thereto from the transferrer T. The plate itself prevents the coloring-matter from passing onto the upper by the construction herein shown, and the guard also acts as a guide for the operator in manipulating the shoe.

When the shoe is held with the edge of its sole against the transferrer, the combined guard and guide plate 70 will be pushed upwardly a distance corresponding to the width of the exposed top portion of the sole. The guard-plate is held in parallelism with the outer end of the transferrer T by means of a slotted plate 60,secured to the bottom plate D, the rear part of the plate entering and moving up and down in the slot 61. (See Fig. 2.) The guard is used for plain work and about the shank of the boot or shoe 3 but if fairstitchwork is being handled not only must the upper be protected, but also the stitching at the top of the sole, and in doing such work the handle e is turned to close the communication between the ports 0 and 0 so that the coloring-matter cannot pass from the reservoir into the chamber of the guard-plate. The operator holds the boot or shoe with the edge of the sole pressed up against the edge of the rotating transferrer and with the edge of the guard-plate in the crease between the sole and the upper, so that the transferrer will apply the coloring-matter evenly and rapidly to the sole edge as it is turned to present new portions thereto, the guard-plate efiectually protecting the upper, the movement of the boot or shoe being toward the operator.

The term coloring-matter herein used includes blacking or other coloring-matter or stain which is to be applied to the edge or the upper portion of a boot or shoe sole.
